What to look at before Shopping for the best Japanese Whetstone?

There are several factors that help you find the best Japanese whetstones. In this section, we will explain all those features!


Whetstones appear in different sizes. Depending on your purposes, you will decide the suitable stone dimensions.

For example, if you only need a product to sharpen regular kitchen knives, then a small whetstone can already serve your needs well.

On the other hand, you need a bigger whetstone for sharpening chef knives or cleavers.

Grit Grade

Different whetstones have different grit particles. The stone with a specific amount of grit will work for many tasks, such as rough grinding, sharpening, and refining the knife edges.

Most knives available on the market are labeled with the number of grit grades. However, some models have the number replaced by the level. For example:

  • Rough: The grit is from 120 to 140
  • Medium: The grit is from 700 to 3000
  • Smooth: The grit is from 3000 to 10000

– Rough Whetstones

A rough stone is commonly used for fixing the chipped edges of a knife. If you notice chips on the blade or your knife blade becomes very dull, we advise you to use the stone at the rough level.

– Medium Whetstones

Most homeowners choose a medium whetstone. This level is suitable for general sharpening.

You can use this type of whetstone to sharpen your knife every time before cooking.

– Smooth Whetstones

A smooth whetstone is more likely to be used for Japanese chef knives. It can help you get rid of all the scratches on the surface of the knife blade, thereby making it look smoother.

In some special cases, many people use the smooth whetstone to buff and polish the knife blade.

Types Of Whetstones

There are 3 common types of whetstones on the market. You can easily distinguish the type by checking the material of the stone.

In detail, here are the features of every type of whetstones:

– Natural Whetstones 

As the name describes, a natural whetstone is mined from natural materials.

In Western nations, people usually use the Novaculite rock, also known as Arkansas stone, to make this sharpening product. This material is solid and can last for a long period of time.

On the downside, Novaculites stones do not support fast sharpening. You need to lubricate this item with oil or water before sharpening the knife.

In Japan, the manufacturers often use sedimentary rock to make the whetstones. Compared to Arkansas rocks, this sedimentary is softer and less durable.

But on the positive side, the Japanese stones enable faster lapping. You can trust them for quick sharpening knives.

A cool thing is, the sedimentary rock only gets along well with water, not oil. Due to this reason, people call Japanese whetstones water stones.

Synthetic Whetstones

Synthetic rocks have another name, which is artificial whetstones. This type of stone can work at a higher consistency than natural rocks.

This synthetic item is usually a combination of aluminum oxide and silicon carbide. The manufacturers can stick these 2 materials together using a binding agent (clay/resin/glass).

– Diamond Plates

As you know, diamond is the hardest mineral material on Earth. A whetstone with diamond plates is ideal for sharpening any other solid object.

Some people can even use diamond plates to fix uneven water stones. Although this type of stone is quite expensive, it can last for multiple years.


There are 2 styles of whetstones – single grit stones and multi-grit stones.

The single stone has only 1 grade of grit on its body.

On the other side, a multi-grit stone (combination stone) is divided into 2 sides. Each part has a different amount of grit. For example, you can find a 1000/6000 whetstone on the market.

FAQs on the whetstones

Below are some common questions you may have while finding the best Japanese whetstones.

#1:  Is 1000 Grit Stone Enough?

If you need a whetstone for sharpening home knives, 1000 grits are more than enough. A 1000-grit stone can help you make super sharp edges for dull knives.

For advanced tools other than a home knife, we recommend a stone that has 2000 – 3000 grits.

#2: What Angle Do You Sharpen A Knife On A Whetstone?

The perfect angle, where the edge of a knife meets the stone, is 22 ½ degrees. Whether you use the whetstone for sharpening a home knife or a chef knife, always do the work at this angle!

#3: Do You Need Two Whetstones?

Normally, you require a minimum of 3 whetstones for sharpening a knife. Each stone will work for the following different purposes:

  • 1 stone for rough-grinding the knife
  • 1 stone for sharpening the knife
  • 1 stone for honing the knife

But nowadays, there is a special type of combination sharpening stone that can support the 3 above works.

#4: Do You Need To Soak A Whetstone?

Our answer is yes. Before sharpening a knife, you should soak the whetstone in either water or oil. These wet substances can help the stone hold the grit in suspension better.

#5: How Do You Clean A Whetstone After Use?

It is quite simple to clean a whetstone after use. All you need to do is rinse the stone under the tap water. 

While rinsing the stone, you should use your hands or a towel to get rid of all the leftover debris or metal fillings on it. The rinsing process should be from 60 – 120 seconds.

After you complete cleaning, don’t forget to pat the stone dry with paper or towel! 

#6: Are All Whetstones Created Equal?

Our answer is no. As you know, whetstones come up with different amounts of grits. The common stones on the market usually have grit from 1000 to 8000. Each grit works for different purposes.

  • 1000 grits are usually for repairing knives with chipped edges
  • 1000 grits – 3000 grits work greatly for sharpening a dull knife
  • Above 4000 grits are ideal for knife-edge refining

#7: Are Whetstones Better Than A Sharpener?

When it comes to sharpening time, a sharpener is better. You need a lot of time to sharpen a knife with a whetstone.

However, a sharpener can not give a great result as whetstones can. A knife usually gets the razor edge when it is sharpened with a stone.

#8: How to use whetstone to sharpen knife?
